Perseus

Obsidian is great for humans. For AI agents, it's a square peg. Here's why I built Perseus Vault — a single-binary, encrypted, local-first persistent memory engine purpose-built for agents.

StackScope is a free public catalogue of indie launches. We find launches on Product Hunt, Hacker News and similar feeds, then crawl each site to detect its tech stack and score it for launch readiness: DNS, security headers, SEO basics. This page is what we saw on 15 July 2026; the live site may have changed since.

Perseus is partway there, with a thorough launch checklist, fast page loads, and clean crawl signals. Worth fixing first: missing several security headers, incomplete legal pages, and incomplete email security.

Launched on Hacker News on July 15, 2026. The site is hosted on GitHub Pages and served through Cloudflare, with a domain registered 7 weeks before launch. The crawl picked up 8 technologies on this site, covering CDN, ai api, DNS providers, and business email. The stack includes Anthropic, Cloudflare, and Cloudflare DNS.

For context, it's running the same core stack as 1,701 other launches.

This score is based on structural patterns and is not definitive. Many legitimate sites may trigger signals, and AI-built sites may go undetected. It should be treated as an indicator, not a verdict.
